Meet Amazon DynamoDB

Explore Amazon DynamoDB, AWS's serverless NoSQL database designed for speed and scalability. Ideal for high-traffic apps, IoT, or gaming, it handles millions of requests per second with low latency — all without infrastructure concerns.

Why Choose DynamoDB?

DynamoDB is a serverless NoSQL database, meaning:

• No servers to provision, patch, or manage;
• Automatic scaling based on your application's needs;
• Pay only for what you use with flexible pricing models.

It's especially useful when you need to store:

• Key-value pairs (like a dictionary/map);
• JSON-like documents (flexible schemas);
• Need to store low-latency write and read operations.

Core Concepts

Tables, Items, and Attributes

• Data in DynamoDB is stored in tables;
• Each table contains items, which are similar to rows in relational databases;
• Each item is composed of attributes, which are like columns—but the structure can vary between items;
• There's no fixed schema, making it flexible for evolving data models.

Keys

Every table requires at least a:

• Partition key: determines how data is distributed across internal partitions;
• Sort key (optional): enables multiple items to share the same partition key but be distinguished and sorted by this value.
